A study of DSRC jammer in vehicle safety application testbed

Dedicated Short Range Communication (DSRC) is a key enabling technology for the next generation of communication-based safety applications. One of the important problems for DSRC deployment is maintaining high performance under heavy channel load. Many studies use NS-2 to simulate hundreds vehicles for packet congestion. But in this paper we built on three DSRC WAVE Boxes and one PC. Two devices located in roadside, one located in vehicle. The communication protocol of the DSRC device which set to converter mode is USER Datagram Protocol(UDP). We follow SAE J2735 for message format. The purpose of this standard is to support interoperability among DSRC applications. We installed three WAVE Boxes and PCs in ARTC´s test-bed. We set a WAVE Boxes to be a jammer. The jammer can simulate many cars to interfere the communication. After experimented, we can understand the issues needed to consider for the design of the DSRC radio test under heavy channel load, providing the designers for reference in the future not only to solve problems but also help to setup a test-bed for testing DSRC radio under heavy channel load.
